What are the different types of fuselage structures?

The predominant types of fuselage structures are the monocoque (i.e., kind of construction in which the outer skin bears a major part or all of the stresses) and semimonocoque. These structures provide better strength-to-weight ratios for the fuselage covering than the truss-type construction used in earlier planes.

What is a truss type aircraft?

Truss—A fuselage design made up of supporting structural members that resist deformation by applied loads. Monocoque—A shell-like fuselage design in which the stressed outer skin is used to support the majority of imposed stresses. Monocoque fuselage design may include bulkheads but not stringers.

What are the defects of truss type fuselage?

The main drawback of truss structure is its lack of a streamlined shape. In this construction method, lengths of tubing, called longerons, are welded in place to form a well- braced framework.

What are the structural components of fuselage?

1 Fuselage/Pressure Cabins. The fuselage of a transport aircraft is a cylindrical shell consisting of the skin, longitudinal stringers and longerons, and transverse frames and bulkheads.

What are the different requirements for designing a fuselage?

A well designed fuselage will ensure that the following are met: The intended payload is adequately and efficiently housed….

  • The maximum cross-sectional area of the fuselage.
  • The fuselage slenderness ratio (ratio of length-to-diameter).
  • The total wetted area of the fuselage.

How many types of trusses are there?

There are two basic types of truss: The pitched truss, or common truss, is characterized by its triangular shape. It is most often used for roof construction. Some common trusses are named according to their “web configuration”.

What is a fuselage construction?

1 Fuselage. The fuselage is a long cylindrical shell, closed at its ends, which carries the internal payload. The dominant type of fuselage structure is semimonocoque construction. These structures provide better strength-to-weight ratios for the central portion of the body of an airplane than monocoque construction.

What part of the plane is the fuselage?

The fuselage or body of the airplane, holds all the pieces together. The pilots sit in the cockpit at the front of the fuselage. Passengers and cargo are carried in the rear of the fuselage. Some aircraft carry fuel in the fuselage; others carry the fuel in the wings.

What is a truss type fuselage?

Often used in lightweight aircraft, a truss structure fuselage is typically made of welded steel tube trusses (though it can also be made of wood). They are often rounded and feature lightweight stringers to achieve a greater aerodynamic shape.

How do you size a fuselage?

The length of your fuselage should be sized according to the maximum cross-sectional area. A slenderness ratio (length-to-diameter) of between 5 and 6 produces the minimum drag case. The location of doors and windows on the fuselage is another important consideration that must be carefully studied.
